Platelets News and Research

A new study by researchers at University of California, San Diego School of Medicine reveals a protein's critical - and previously unknown -- role in the development and progression of acute myeloid leukemia (AML), a fast-growing and extremely difficult-to-treat blood cancer. [More]

Immune thrombocytopenia, or ITP, is an autoimmune disease whereby the immune system sends antibodies to attack and destroy the body's platelets--blood cells responsible for controlling bleeding. [More]

Today AbbVie announced the European Commission granted marketing authorization for IMBRUVICA (ibrutinib) as the first treatment option available in all 28 member states of the European Union for the treatment of Waldenstrom's macroglobulinemia (WM), a rare, slow growing blood cancer, in adult patients who have received at least one prior therapy, or in first line treatment for patients unsuitable for chemo-immunotherapy.

NIBIB-supported researchers have created tiny gel particles that can perform the same essential functions as platelets. The particles could one day be used to control excessive bleeding following traumatic injury or in individuals with impaired clotting due to an inherited condition or as a result of certain medications or chemotherapy. [More]

University of California San Francisco scientists have identified characteristics of a family of daughter cells, called MPPs, which are the first to arise from stem cells within bone marrow that generate the entire blood system. The researchers said the discovery raises the possibility that, by manipulating the fates of MPPs or parent stem cells, medical researchers could one day help overcome imbalances and deficiencies that can arise in the blood system due to aging or in patients with specific types of leukemia.

Two medical researchers from the Children's Hospital of Michigan and the Wayne State University School of Medicine have published the results of a nearly 10-year investigation that identified a key gene mutation that can trigger acute lymphoblastic leukemia, or ALL, and several other types of cancer.

The concept sounds like the stuff of science fiction: take a pill, and suddenly new tissues grow to replace damaged ones. Researchers at Case Western Reserve and UT Southwestern Medical Center this week announced that they have taken significant steps toward turning this once-improbable idea into a vivid reality. [More]

Blood research conducted by biomedical engineers from The University of Texas at San Antonio College of Engineering, in collaboration with the Blood Research Program of the U.S. Army Institute of Surgical Research, could change the way injured soldiers are treated on the battlefield. [More]

Blood clots often form when lipid-rich plaques on the inner surface of arteries rupture and platelets aggregate at the site of injury. Cardiologists from Ludwig-Maximilians-Universitaet in Munich have now compared the effects of two new platelet aggregation inhibitors. [More]

Janssen Research & Development, LLC announced data from the Phase 3 multicenter study SAR3007, which demonstrated a significant improvement in progression-free survival with trabectedin (YONDELIS®) compared to dacarbazine in patients with advanced liposarcoma (LPS) or leiomyosarcoma (LMS) previously treated with an anthracycline and at least one additional chemotherapy regimen. [More]

Pharmacyclics LLC today announced interim results from the ongoing Phase Ib/II PCYC-1129 study suggesting that ibrutinib (IMBRUVICA) may be a safe and effective treatment for patients with chronic graft-versus-host-disease (cGVHD) who were either refractory to steroid treatment or were steroid-dependent. [More]

Today, Pharmacyclics LLC announced the results of the Phase III HELIOS trial (CLL3001), which found that patients with previously treated chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who received ibrutinib (IMBRUVICA) in combination with bendamustine and rituximab (BR) experienced an 80% reduction in the risk of progression or death compared to patients receiving placebo in combination with BR. [More]

Use of the targeted agent pacritinib significantly reduced the symptoms and burden of advanced myelofibrosis in patients, says a Mayo Clinic researcher who co-led PERSIST-1, the worldwide phase III clinical trial that tested the therapy. Specifically, pacritinib substantially reduced severe enlargement of the spleen, a typical feature of advanced myelofibrosis, in more than 20 percent of patients and alleviated debilitating side effects in more than 46 percent. [More]

CTI BioPharma Corp. and Baxter International's Bioscience business today announced data from PERSIST-1 – a randomized Phase 3 registration-directed trial examining pacritinib for the treatment of myelofibrosis – in a late-breaking oral session at the 51st Annual Meeting of the American Society of Clinical Oncology, May 29-June 2, 2015 in Chicago, Ill. [More]

Eli Lilly and Company announced final results of the Phase III PROCLAIM trial that will also be discussed in an oral presentation at the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago. [More]

Traumatic injury is the leading cause of death among people under age 45, but if trauma physicians could deliver plasma to these injury victims within minutes of their arrival in the emergency room, more of them would stand a better chance of survival. [More]

Verax Biomedical today announced that the company has gained FDA clearance to expand the use of its Verax Platelet PGD test—a rapid test for the detection of bacterial contamination in platelets intended for transfusion. The new FDA clearance makes the Verax Platelet PGD test the only rapid test on the market cleared by the FDA to check every commonly distributed platelet type in the United States. [More]
